ISS
Amateur radio aboard the International Space Station: voice, packet and scheduled image transmissions. Modes and availability can change.
ARISS station status ↗Orbits. Passes. Radio from above.

The station overhead. The signal on the horizon.
Track the ISS and a small selection of amateur-radio satellites. Watch the ground track, then check whether the radio is actually operating.
ABOVE THE HORIZON
One orbit. A moving window.
Choose a satellite using Select beneath the map.
The track moves automatically while the view is running.
ORBIT TRACK / N2YO
Map, orbit calculations and pass predictions: N2YO. Positions are calculated from orbital elements, not live GPS telemetry. The provider estimates the observer’s location from the visitor’s IP address; verify it in the full tracker before using pass times. Compact screens show the map without the pass table. The provider’s privacy and cookie policies apply.
The circle is a geometric horizon footprint, not a guarantee of radio coverage. For local pass planning, check the observer location, time zone, elevation and current satellite status in the source tools.
THE SHORTLIST
A few familiar voices.
Orbit tracking is always separate
from the radio’s operating status.
SO-50
SaudiSat-1C, an amateur FM repeater satellite. Check AMSAT’s operating notes and recent reception reports before a pass.
FM satellite reference ↗AO-91
Fox-1B / RadFxSat. AMSAT’s battery guidance calls for sunlight-only access; seeing it on the map does not mean the repeater is available.
Check operating restrictions ↗RS-44
DOSAAF-85 carries a linear amateur-radio transponder. Follow the frequency reference and current reports for operating details.
Linear satellite reference ↗BEFORE THE PASS
A position isn’t
a reception report.
The map predicts where a spacecraft is. Operator schedules, power, antenna geometry and your horizon determine what you can hear.
Read current AMSAT reception reports ↗Calculated positions / a continuously moving track
N2YO propagates orbital elements forward in time to draw the current position. The spacecraft is not sending rack.org a live location. Accuracy depends on the age and quality of the orbit data.N2YO: tracking data and limitations ↗
Radio passes / include daylight and darkness
The tracker includes passes that are not optically visible. A useful radio pass does not require a visible spacecraft. Local pass times still require a correct observer location.AMSAT pass predictions ↗
Operating status / check the source
Amateur satellites may use schedules, switch modes or have power restrictions. The current-status links open the providers’ latest information; the cards above are reference notes, not live availability indicators.AMSAT live status ↗
